I bleed even when not on my period

Hydi

when I'm with a guy and he fingers me really rough, I bleed. This has happened on more than one occasion and with more than one guy. It's not like it's every time I get fingered, just when going super rough. Idk what to do or if it's okay and I can't talk to a gynecologist about it because I would have to talk to my mother due to me bring under 18
